A stand-alone module for localizing a surveying device installed with a stand above a ground mark. The module has at least one housing attached between the stand and the surveying device, a measuring camera unit, which is arranged and designed in such a way that when the module is mounted on a stand the ground mark can be detected in the field of view of the measuring camera unit, a power supply, an inclination sensor and a communication unit.
Legal claims defining the scope of protection. Each claim is shown in both the original legal language and a plain English translation.
3. The stand-alone module according to claim 2, wherein the deflection unit is moved by motors or the deflection unit is moved manually by a user.
A stand-alone module is designed for precise positioning and alignment in mechanical or optical systems. The module includes a deflection unit that adjusts the position or orientation of a component, such as a mirror, lens, or mechanical arm, to achieve accurate alignment or movement. The deflection unit is movable to redirect or reposition the component as needed. The movement of the deflection unit can be controlled by motors, allowing for automated and programmable adjustments. Alternatively, the deflection unit can be moved manually by a user, providing flexibility in applications where automation is not required or practical. The module operates independently, meaning it does not rely on external systems for its core functionality, making it suitable for integration into various devices or systems where precise positioning is critical. The motorized or manual movement options ensure adaptability to different operational environments and user preferences. This design enhances versatility, allowing the module to be used in applications such as optical systems, robotics, or precision manufacturing where controlled deflection is necessary.
4. The stand-alone module according to claim 1, wherein the stand-alone module comprises a tribrach with one, two, or three manually adjustable adjustment screws.
This invention relates to a stand-alone module for surveying or measurement applications, specifically designed to improve the precision and ease of alignment in optical or laser-based instruments. The module addresses the challenge of achieving accurate positioning and leveling in field conditions, where manual adjustments are often required to compensate for uneven surfaces or misalignment. The stand-alone module includes a tribrach, a component used to securely mount and align surveying instruments such as total stations or theodolites. The tribrach is equipped with one, two, or three manually adjustable adjustment screws, allowing fine-tuning of the module's orientation. These screws enable precise horizontal and vertical adjustments, ensuring the instrument is properly leveled and aligned with the target. The module may also include a base plate for stable mounting and a clamping mechanism to lock the instrument in place once adjustments are complete. The design allows for quick and accurate setup, reducing the time and effort required for field measurements. The adjustable screws provide flexibility in different terrains, ensuring reliable performance across various applications.
5. The stand-alone module according to claim 1, wherein the localization unit is configured such that, based on a coarse position of a current location of the stand-alone module, either provided or determined by the stand-alone module, the localization unit queries a local or cloud database of ground marks at or around the current location, and on the basis of the database an external coordinate system is assigned to the ground mark at the current location.
6. The stand-alone module according to claim 1, wherein the stand-alone module further comprises an electronic compass, and the localization unit incorporates azimuthal information from the compass in a localization.
This invention relates to a stand-alone module for localization, addressing the challenge of accurately determining position in environments where traditional navigation systems may be unreliable or unavailable. The module includes a localization unit that processes signals from external sources, such as satellites or terrestrial beacons, to estimate position. To enhance accuracy, the module incorporates an electronic compass that provides azimuthal (directional) information. The localization unit integrates this compass data with other positional inputs to refine the localization process, improving directional precision and reducing errors in position estimation. This integration is particularly useful in scenarios where signal interference or multipath effects degrade traditional localization methods, such as in urban canyons or indoor environments. The compass data helps correct drift and misalignment, ensuring more reliable navigation. The module operates independently, without relying on external infrastructure, making it suitable for applications in autonomous vehicles, robotics, and portable navigation devices. The combination of signal-based localization with compass-derived azimuthal information provides a robust solution for accurate positioning in challenging conditions.
7. The stand-alone module according to claim 1, wherein the field of view of the measuring camera unit is arranged centrally right through the stand.
8. The stand-alone module according to claim 1, wherein the field of view of the measuring camera unit is arranged past and to the side of a stand shoulder or a stand plate of the stand and is aligned in the direction of the ground point.
10. A target plate designed to provide substantially horizontal support on a ground mark for use with a stand-alone module according to claim 1.
12. A system consisting of a surveying device with an integrated stand-alone module according to claim 1.
